Which type of reaction are given by alkanes
Correct answer: B. Substitution
- A. Addition
- B. Substitution
- C. Elimination
- D. Polymerization
Explanation
Alkanes typically undergo substitution reactions where one or more hydrogen atoms in the alkane molecule are replaced by other atoms or groups. This is due to the relatively low reactivity of alkanes, making them more prone to substitution rather than addition or elimination reactions.Option A is incorrect because alkanes do not generally undergo addition reactions. Option C is incorrect because alkanes are not known for elimination reactions. Option D is incorrect because alkanes do not usually undergo polymerization reactions due to their saturated structure and lack of reactive functional groups.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
